      trend??? by Ericsson Polarized antenna setups for SDMA by polarization. Thus only long term CQI is needed and less inter-stream interference. For DFT beamforming unitary precoding is better than non-unitary precoding when using less-bit quantilized codebook.

Embracing wireless interference - 0 views

  • Embracing wireless interference: analog network coding
  • ABSTRACT Traditionally, interference is considered harmful. Wireless networks strive to avoid scheduling multiple transmissions at the same time in order to prevent interference. This paper adopts the opposite approach; it encourages strategically picked senders to interfere. Instead of forwarding packets, routers forward the interfering signals. The destination leverages network-level information to cancel the interference and recover the signal destined to it. The result is analog network coding because it mixes signals not bits. So, what if wireless routers forward signals instead of packets? Theoretically, such an approach doubles the capacity of the canonical 2-way relay network. Surprisingly, it is also practical. We implement our design using software radios and show that it achieves significantly higher throughput than both traditional wireless routing and prior work on wireless network coding.

    People have already used this tech in audio system. Why can't we use it in digital system?

  • You have to understand that this is a horrible environment for a radio channel. There’s interference, all sorts of multipath and an infinite number of different path loss issues.
  • provide similarly marginal signal levels, add a bit of interference from other nearby base stations, throw in some fading, and throughput will drop substantially
  • how well it lends itself to assuring that such optimal conditions are more the norm than the exception
  • ...1 more annotation...
  • you should not assume, based upon announcements of “successful trials,” that they have been fully resolved

    This problem is tough!
